LAST YEAR: Raiders plummeted from 12 wins in 2016 to six last year as QB Derek Carr and offence regressed, defence struggled, and coach Jack Del Rio was fired. Oakland’s offensive output dropped by more than seven points per game, takeaways fell from 30 to 14, and Raiders got almost no production from past three draft classes in becoming one of league’s biggest disappointments. That led to move to bring coach Jon Gruden back for second stint with Raiders after spending past nine seasons in broadcast booth.

CAMP NEEDS: Biggest priority is getting 2016 Defensive Player of Year Khalil Mack into camp after he held out entire off-season while seeking long-term contract. Mack is entering final year of rookie deal and Gruden and new DC Paul Guenther are eager to get most important defensive piece on practice field. Other main issues are learning Gruden’s system and figuring out offensive tackle situation with LT Donald Penn coming back from foot injury and rookies Miller and Brandon Parker battling Breno Giacomini for time.

EXPECTATIONS: Owner Mark Davis has wanted to bring back Gruden ever since taking over team seven years ago. He’s hoping move pays off in team’s final two seasons in Oakland before move to Las Vegas in 2020. Gruden is being counted on to bring out best from Carr, who went from MVP candidate in 2016 to mediocre last season as he dealt with injuries. His protection got worse and his receivers were inconsistent. Even if Gruden does manage to spark offence, defence will need to take big step forward for Raiders to get back into playoff contention.
